研究了电磁场下低功率激光束的聚束和偏转特性。实验中根据法拉第效应设计并实现了圆柱形电磁腔。几种类型的磁光元件分别放置在电磁腔中。在小功率激光器偏转特性测试中，采用偏振消光的方法测量了线偏振光通过电磁腔后的偏振面的旋转角度。我们重点关注线圈电流与旋转角度之间的关系。实验数据表明，当线圈电流在0~5 A范围内变化时，旋转角度从0°变化到24.1°。然后，利用最小二乘算法根据实验数据得到线圈电流与旋转角度的拟合公式。分析表明，旋转角度与励磁电流成正比，相关系数大于0.9995。为了研究低功率激光的光束聚束特性，测量了低功率激光通过电磁腔后激光光斑的面积。实验数据表明，激光光斑面积变化范围较小，实验数据满足3σ标准。
The bunching and deflection characteristics of low-power laser beam were investigated under electromagnetic field. On the basis of the Faraday effect, the cylindrical electromagnetic cavity was designed and implemented in the experiments. Several types of the magneto-optical elements were placed in the electromagnetic cavity individually. In the test of the deflection characteristics of low-power laser, the rotating angle, the polarization plane of linearly polarized light which passed through electromagnetic cavity, was measured by polarization extinction. We focus on the relation between the coil current and the rotating angle. The experimental data show that when the coil current varies in the range of 0–5 A, the rotating angles changed from 0° to 24.1°. Then, a fitting formula about the coil current and the rotating angle was obtained from the experimental data using the least square algorithm. The analysis shows that the rotating angle is proportional to the excitation current and the correlation coefficient is more than 0.9995. In order to study the beam bunching characteristics of low-power laser, the area of the laser facula was measured after the low-power laser passed through the electromagnetic cavity. The experiment data show that the laser facula area changes in a small range and the experimental data meet 3σ criteria.
